Protection and Control • Excellent migration product when pilot wire protection is changed to fibre or multiplexed comms • Maximises connection of renewables for up to 6 line or cable ends • Full support of SONET/SDH channel switching • Suitable for direct fiber and multiplexed (IEEE C37.94) networks, including MPLS systems Application Flexibility • Ability to take an end off-line for maintenance • Back-up protection, reclosing, measurements and recording as per P141-P145 and P14N/D products - no need to retrain • Easy scheme customisation with programmable scheme logic and LEDs • Extensive binary signalling capability between ends for intertripping, breaker fail, interlocking and control/observation of remote 3rd party substations Advanced Communications Distribution Dual and Multi-Ended Current Differential Network Challenges - Economical Line Differential For many years the distribution networks have used pilot wire differential protection. Pilot wire line differential protection compares the currents entering and leaving the protected zone via a pair of pilot wires. As technology has advanced, copper pilot wires are being replaced by fibre links between substations, offering safer and higher bandwidth communications paths, with simpler inherent self-supervision. Also, as the distribution power networks evolve to transport power in evermore complex ring and multi-terminal networks, line/cable differential protection becomes increasingly attractive, with its inherent ability to address grading/selectivity challenges. Finally it offers scalability for multi-terminal circuits to accommodate many distributed generation connections or new load taps along the line. GE’s multi-ended current differential protection provides an excellent migration product when pilot wire protection is changed to fibre or multiplexed communications. The relays are ready for any protection topology from two to six terminals, whether those multiterminals exist now, or are provisioned for connection in the future. For distribution networks, two compact, economical models, P54A and P54B are available in a half rack 40TE case size. MiCOM Agile P54A/B Distribution Line/Cable Differential For applications where VT inputs are not available, or where simplicity is preferred, the P54A model is the perfect choice. The P54A backup protection operates non-directional. The sister P54B model has an additional 4 VT inputs to support autoreclose with check synchronization, and directionalised backup protection. Both models offer three-pole trippings. The P54A/B relays support IEC 61850 Edition 2, SNMP v3 and IEEE1588, opening deployment possibilities in today’s digital substations. PRP, HSR and RSTP redundant Ethernet station bus communications are also supported.

Backup Feeder Protection Highly-selective protection for overhead lines and underground cables with three phase tripping. Maximises connection of renewables or distribution tapped loads for up to 6 line or cable ends In addition to the differential protection, the P54A/B provide integrated feeder back-up protection in the same box. This make the P54A/B a perfect one box solution for economical distribution protection applications. Fast operating time, less than 1 cycle for up to 4 ends, 1.25 cycles for 5 or 6 ended Negative sequence overcurrent and SEF (0.5% In sensitivity) Economical - no...
